Shevi'is5: 3
לוּף שֶׁעָבְרָה עָלָיו שְׁבִיעִית — רַבִּי אֱלִיעֶזֶר אוֹמֵר: אִם לָקְטוּ הָעֲנִיִּים אֶת עָלָיו, לָקָטוּ; וְאִם לָאו, יַעֲשֶׂה חֶשְׁבּוֹן עִם הָעֲנִיִּים. רַבִּי יְהוֹשֻׁעַ אוֹמֵר: אִם לָקְטוּ הָעֲנִיִּים אֶת עָלָיו, לָקָטוּ; וְאִם לָאו, אֵין לָעֲנִיִּים עָלָיו חֶשְׁבּוֹן.
A luf which grew past the seventh [year] — R’ Eliezer says: If the poor picked its leaves, they have [been] picked; but if not, he must make an accounting with the poor. R’ Yehoshua says: If the poor picked its leaves, they have [been] picked; but if not, the poor have no accounting with him.
